Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive multiple spatial dimension multiplexed (SDM) communications via a single antenna panel of the UE. The UE may perform phase noise correction for the multiple SDM communications based at least in part on phase tracking reference signals received via a single communication of the multiple SDM communications. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving multiple spatial dimension multiplexed (SDM) communications associated with multiple transmission reception points (TRPs) via a single antenna panel of the UE;
- estimating a phase noise based on phase tracking reference signals (PT-RSs) received via a single communication of the multiple SDM communications;
- and
- performing phase noise correction for the multiple SDM communications based at least in part on estimating the phase noise received via the single communication of the multiple SDM communications.
A method of wireless communication performed by a base station, comprising:
- determining that a user equipment (UE) is to receive multiple spatial dimension multiplexed (SDM) communications associated with multiple transmission reception points (TRPs) via a single antenna panel of the UE;
- configuring a single TRP, of the multiple TRPs, to transmit phase tracking reference signals (PT-RSs) with a single communication, of the multiple SDM communications, for the UE to use for phase noise correction of the multiple SDM communications;
- and
- sending, to the UE, configuration information indicating that the UE is to estimate and correct phase noise for the multiple SDM communications received via the single antenna panel based on the PT-RSs of the single communication.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- receive multiple spatial dimension multiplexed (SDM) communications associated with multiple transmission reception points (TRPs) via a single antenna panel of the UE;
- estimate a phase noise based on phase tracking reference signals (PT-RSs) received via a single communication of the multiple SDM communications;
- and
- perform phase noise correction for the multiple SDM communications based at least in part on estimating the phase noise received via a single communication of the multiple SDM communications.
A base station for wireless communication, comprising:
- a memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:

- and
- configure a single TRP, of the multiple TRPs, to transmit phase tracking reference signals (PT-RSs) with a single communication, of the multiple SDM communications, for the UE to use for phase noise correction of the multiple SDM-communications, and
- send, to the UE, configuration information indicating that the UE is to estimate and correct phase noise for the multiple SDM communications received via the single antenna panel based on the PT-RSs of the single communication.
